Over the last 4 years I have worked very closely with Hilary Vernon, Informed Designs, to make sure my horses were in the correct bits for their full comfort. In doing this I have moved my dressage Pony (Carbon Copy) from low level Elementary to Advanced Medium. We started him in the Harmony snaffle to encourage him to push in to the contact. He has just moved on to the double bridle which I feel has helped him lift his frame and encourage him to use his hind legs. Another horse was my hunt horse that went from a gag, as could not stop him, to the Symmetry snaffle as he was comfortable so stopped running from my hands. Then there is the 4 by 4 (Zazoo) my mums horse, when changing her bit to the Doubler mouth piece with hanging cheek for dressage and Pelham for jumping, changing her bits had little effect to her dressage scores but is now much happier to have her bridle put on, before she would squash you to the wall and lift her head in the air.
